[0026] like Figure 1 and Figure 2 As shown, the tobacco gas lock disassembly and assembly device provided in this embodiment includes: a movable platform 2, on which a liftable small platform 1 and a liftable medium platform 3 are provided. The liftable small platform 1 is used to place a speed reducer 9, and the liftable medium platform 3 is used to place a gas lock 4. The top surface area of ​​the liftable small platform 1 is smaller than the top surface area of ​​the liftable medium platform 3, and the height of the liftable small platform 1 is greater than the height of the liftable medium platform 3. Furthermore, the axis directions of the speed reducer 9 and the gas lock 4 are located in the same horizontal plane.

[0027] Since the bottom areas of the air lock 4 and the reducer 9 are different, with the reducer 9 having a smaller bottom area and the air lock 4 having a larger bottom area, this utility model designs two liftable platforms of different areas: a small liftable platform 1 and a medium liftable platform 3, in order to reduce space occupation and facilitate transportation. Both the small liftable platform 1 and the medium liftable platform 3 are installed on the upper surface 21 of the movable platform 2, and the two are aligned in the longitudinal direction of the upper surface 21.

[0028] Furthermore, the movable platform 2 includes an upper platform 21, and four legs 22 are arranged vertically below the upper platform 21. Each leg 22 is provided with a caster wheel 23, and a cross brace 24 is provided between adjacent legs.

The third and fourth lifting rods on the same side are connected together by a bushing to form a second scissor structure, which can rotate relative to each other.
